Satellite Licenses for the Cisco TelePresence System

Revised: February 2012, OL-21845-01

The information in this appendix explains how to order satellite licenses and how to configure both Cisco Unified Communications Manager (Unified CM) and Cisco TelePresence System (CTS) to support satellite functionality. This appendix contains the following sections:

Cisco TelePresence over Satellite Networks

The Cisco TelePresence over Satellite Networks solution extends the reach of Cisco TelePresence to remote, tactical locations where terrestrial bandwidth is not available. This solution incorporates existing Cisco TelePresence endpoint and infrastructure products with new software releases designed to function more effectively on poor, high-delay networks.

Supported CTS Devices

The CTS 1000, CTS 1100, CTS 1300, and CTS 500 endpoint models are supported as the remote endpoint on the far end of a satellite link.

Other endpoint models (CTS 3000 and CTS 3200) have not been qualified to work on the remote side of a satellite link because the bandwidth needed for these three-screen systems quickly becomes cost-prohibitive to run over satellite networks. Any Cisco TelePresence endpoint or mix of endpoints (for a multipoint call) can be used on the terrestrial side of the satellite link.

Supported CTS Software

You must be running CTS software version 1.5 or a later release on all Cisco TelePresence endpoints, Cisco TelePresence Multipoint Switches, and Cisco TelePresence Managers within your network to participate in a satellite call.

Supported Satellite Bandwidth

You will need a minimum of 3-MB bandwidth (at 720p, good motion handling) in a single-channel-per-carrier (SCPC) configuration over a single-hop satellite link.

Note Because the Cisco TelePresence video and audio are traveling up to the satellite and back down to an earth station, significant (500 ms or more) latency is introduced into the signal. The result is noticeable delay in the conversation. In addition, atmospheric conditions or other interference may impact satellite-link performance and introduce jitter or packet loss into the call. The result may be noticeable degradation of the video quality.

CTS software release 1.5 and later releases support satellite deployment configurations that significantly raise the thresholds for network warning messages and call termination. When a satellite endpoint joins a call (point-to-point or multipoint), all other endpoints in the call negotiate the new threshold setting, so no one in the call gets warning messages or gets dropped just because a satellite-based endpoint joins the call.

Satellite Security

Ordering a Satellite License

You can order satellite licenses when you initially order your CTS, or you can purchase separate satellite licenses to upgrade an existing CTS. Note the following details when you order a satellite license:

The product authorization key (PAK) will either be physically delivered to your location or electronically delivered via E-mail.

Product Number:

– Physical: CTS-SATELLITE=

– Electronic: L-CTS-SATELLITE=

Loading a Satellite License

After you have received the satellite license, load it on Unified CM by following these steps:

Caution Do not edit or change the contents of the license or it will become invalid.

Enabling the Satellite Feature

After the satellite license has been loaded on Unified CM, and the CTS satellite endpoints have been identified, you are ready to enable the satellite feature using CTS command-line interface (CLI) commands. For information about using CTS CLI commands, see the Cisco TelePresence System Command-Line Interface Reference Guide.

To enable the satellite feature:

Step 1 Check to see that the satellite license is available. From the CTS CLI admin command prompt, enter the following command:
